/*Write the definition for a class called Rectangle that has floating point data members length and width. The class has the following member functions:
void setlength(float) to set the length data member
void setwidth(float) to set the width data member
float perimeter() to calculate and return the perimeter of the rectangle
float area() to calculate and return the area of the rectangle
void show() to display the length and width of the rectangle
int sameArea(Rectangle) that has one parameter of type Rectangle. sameArea returns 1 if the two Rectangles have the same area, and returns 0 if they don't.*/
